What was more popular than the musicals of the 50’s and 60’s produced by Rogers and Hammerstein ?

Oklahoma! the film from the 50’s was , was based on a same named play from earlier on and was the first feature film photographed in the Todd-AO 70 mm widescreen process. That was apparently films with very high resolution and sounds to me like very high tech for those days.

My favourite song from the film

another O

Oh what a beautiful morning

There’s a bright golden haze on the meadow,
There’s a bright golden haze on the meadow,
The corn is as high as an elephant’s eye,
An’ it looks like its climbin’ clear up to the sky.
